Description

用于安全型电风扇的吸风组件
技术领域
    本发明属于电风扇结构设计技术领域，具体涉及一种用于安全型电风扇的吸风组件。
背景技术
目前市售的无叶型安全风扇，包括底座和设置在底座上的环形出风面罩，底座中设有以涡轮式风机为主的吸风组件；这种风扇的最大优点是由于摒除了传统电风扇所用的扇叶，从而无论对大人还是幼儿均具有极好的安全性。但是这种风扇也存在以下不足之处：为了避免庞大臃肿，采用较小直径的底座，所以限制了涡轮式风机的大小，为了保证足够的出风量，涡轮式风机的转速较高，一般达到每秒几百至上千转，导致噪音很大，且难以根除；另外，由于涡轮式风机的直径太小，虽然其转速很高，但是出风量仍然不能与传统风扇相比，吹风效果不佳。
发明内容
本发明的目的是提供一种噪音较小且出风量较大的用于安全型电风扇的吸风组件。
实现本发明目的的技术方案是：一种用于安全型电风扇的吸风组件，包括壳体、设置在壳体中的吸风机、设置在壳体中的风道；壳体的一端设有作为风道进风口的网孔板，壳体的另一端设有风道出风口。 
上述方案中，还包括电冷片，电冷片设置在风道内且邻接网孔板处。
本发明通过改进吸风组件，使其具有噪音较小且出风量较大，以及能够制冷的优点。
附图说明
图1是本发明的一种结构示意图；
图2是图1所示吸风组件的一种正视图。
具体实施方式
    （实施例1）
本实施例是一种用于安全型电风扇的吸风组件，见图1和图2所示，包括进风组件1和出风面罩2；出风面罩设有进风孔21、导风通道22和出风狭孔23；进风孔设置在出风面罩的背面中心处，出风狭孔设置在出风面罩的正面；进风组件包括壳体11、设置在壳体中的吸风机12、设置在壳体中的风道13；壳体的一端设有作为风道进风口的网孔板14，壳体的另一端设有风道出风口15；风道出风口与出风面罩进风孔连通；出风面罩进风孔处设有安装部24，壳体设有风道出风口的一端固定在该安装部中，。
壳体设有风道出风口的一端的外壁与出风面罩安装部的内壁之间设有密封圈4。
所述吸风机是涡轮风机或具有扇叶的风扇。本实施例所用的是具有涡轮扇叶121的涡轮风机，但是选用普通风扇也是可行的，并且可以有效降低噪音。
本实施例还包括多个电冷片3；电冷片设置在风道内且邻接网孔板处；在具体实践中，也可将电冷片设置在出风面罩内且邻接风道出风口处。
出风狭孔的基本形状呈弧线状，各出风狭孔之间留有间距。
出风狭孔在出风面罩上排列成环状的外出风区25和内出风区26。
显然，本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而这些属于本发明的实质精神所引伸出的显而易见的变化或变动仍属于本发明的保护范围。
